Title: High pressure combustion device
IPC: F23R3/42
Filed: 1992-03-16
Abstract: PURPOSE:To prevent a lowering of pressure resistant strength of a vessel following temperature rise by using a porous body as insulating material and causing oxidizing agent or combustion gas to flow through between the porous body and the vessel. CONSTITUTION:An oxidizing agent or recirculated combustion gas 2 flowing along an inner wall 1 of a combustion vessel flows into a combustion chamber 5 through numerous holes provided in a porous body 3, while the agent or gas cools the body 3 having been heated by radient heat from high temperature combustion gas 4. As a result, the radiant heat from the inner wall 1 of combustion vessel is shielded from the gas 4 so that the temperature of the the body of the vessel is restrained from rising. In this manner, a lowering of pressure resistant strength of the body of the vessel following the temperature rise can be avoided.

IPC: H04N5/335
Filed: 1984-03-28
Abstract: PURPOSE:To suppress blooming and to eliminate dark current by taking out excess electrons accumulated in photodiode to a vertical CCD shift register and sweep them out to the outside. CONSTITUTION:An image pickup area 11 made up of a photodiode 1 and a vertical CCD shift register SR2 and an accumulation area 12 that accumulates temporarily signal charge stored in the photodiode 1 by a selector gate 8, CCD SR9-L, 9-R for accumulation and an output gate 10 are constituted. The light signal charge stored in the area 12 operates the SR2 throughout until completion of scanning. Gates 7-1L, R are always put in the state of slight conduction by applying 1 level of voltage slightly higher than the period in which the light signal charge is transferred to transfer gates 7-1L, R, and excess charge accumulated in the photodiode 1 is taken out forcibly to the SR2. This excess charge is sent out to an excess charge sweep-out drain 13-1 through a sweep out gate 13-2. Thus, blooming can be suppressed, and at the same time, dark current can be eliminated as the dark current accumulated in the SR2 is also swept out.
